Kevin Feige has recently given an interview to ComicBook.com and explained why the fans would have to wait until the release of Spider-Man releases in July 2019.

"As we've been doing for years, we aren't going to announce anything post-Avengers: Endgame or Spider-Man until post-Endgame and Spider-Man," he said.

"As you know as a fan, there's a tremendous amount of potential and a tremendous amount of additional characters and storylines and groups of characters that we're going to keep playing with.

Feige continued:

"And again, that's a testament to Marvel and to the amount of storylines and characters and amazing, amazing runs that have been in the Marvel comics."

Marvel could be secretive about their future projects but the fans have some theories about what is actually on their plate.

The third installment of Guardians of the Galaxy was expected to begin filming this year. This project have been postponed as director James Gunn has left the project. The filming will start in February 2021 instead.

Scarlett Johansson's Black Widow is possibly getting a solo feature film. Moreover, the sequels for Black Panther and Doctor Strange are also considered as a possibility.
